HUMAN LOCOMOTION & MOVEMENT

JOINTS
• Is the place where bones meet & are held together by ligaments. HINGE JOINT • Found in elbows & phalanges of the toes & fingers • Allow the lower leg to swing back & forth • Allow the movement of bones in one plate

MUSCLE INVOLVED IN WALKING
• The calf muscle contracts and raises the heel-it pushes the ball of the foot against the ground by exerting a forward thrust • The hamstring muscle contract to pull the femur back and bend the knee. The leg is raised • The weight of the body is now supported by the left leg since the right foot loses contact with the ground • The quadriceps muscle will contract, pull the femur forward and extends the leg-the thigh is extended • After the extension of the legs, the foot with the heel touching the ground first will regain contact with the ground again • The weight of the body is supported by the right leg. Now the whole sequence is repeated with the left leg
